Allow reading with small uio->uio_resid or uio->uio_offset > 0 from /proc/X/map

Currently map file in procfs cannot be read with programs like cat
sometimes. It happens if the buffer to be read into cannot hold the entire
content of map file. Call to read returns EFBIG on this occasion, which is
somewhat confusing.
